Gas-hydrate formation experiment with automatic steering (zooming to a region of interest with water outflow). (a, b) Sample states in low spatial resolution before (State 0) and after (State 1) water redistribution, respectively. (c) The region of interest in high spatial resolution after water redistribution (State 1). (d) The region of interest with formed gas hydrate (State 2). Bright color corresponds to sand grains and water solution, dark gray/black to methane gas, and light gray in high-resolution images to gas-hydrate.
